My two maybe equal favourites are still to start doing science! The James Webb Space telescope, which I worked on will be launched in 2019. Right now I’m working on The European Extremely Large Telescope, which will be pointed to the sky in 2024. This combination of the biggest and best ground and space telescopes will deliver ground-breaking science. I guess for telescopes working right now, I’ve got a soft spot for VISTA (on Hawaii) which was the first one I worked on.
